The War of Independence had left the fledgling America free, but in turmoil. There was as yet no President and the country was a loose conglomeration of more or less independent states.
Many soldiers who had fought in the war had yet to be paid for it and there was no official center of government to pay them. Philadelphias Old City Hall was the only place the where the leaders of the revolution routinely met and in 1783 they decided it was time to designate a new national capital.
